I love opinions
While everyone loves the 3D look it increases the print cost, and minimum qty, for a number of reasons.
I always suggest that clients maximize their profit by simplifying everything
if they can. Printers don't care if you print a full back on 24 tees and a full front 1 as long as it's exactly the same art. Same goes for a left chest. Tank, Tee, Polo... we could care less as long as the art doesn't change and you meet the minimum qty for the print. The more colors, the higher the minimum qty.
So, with something like the attached, there are only 2 print sizes and they all get combined. Make it even simpler and offer tees with a front only print to reduce the print cost. The few that want a polo are left out but I'm guessing everyone else would give you their money.
